Serial Communication
SuperDrive 6.10 | 58
The RS232 serial cable used for the connection between PC and drive is fitted at one end with a DB9
female connector. The PC connector is a DB9 male connector. If the PC connector is a DB25 male
connector, you must use a DB9/DB25 adapter.
Figure below shows the adapter.

6.4 RS485
DESCRIPTION
The RS485 serial interface is used when the distance between PC and the drive is longer than 10 meters or
when using a network of drives (up to 30 drives). The maximum distance between the PC and the drives is
of 1000 meters.
Some drives (CFW-05, CFW-08, CFW-09 and MVW-01) may be connected directly to the RS485 serial
interface by using an expansion board (optional board).
Other drives (CFW-07, CFW-08, SSW-03, SSW-04, SSW-05, SCA-04, SCA-05 e CTW-04) require the use
of the MIW-02 module.
The use of a RS232 converter is required for the RS485 between the microcomputer and the RS485
network.
CONNECTION
Figure below show how to connect the RS485 serial interface between the PC and the Drives.
